I can see why some pros might do it, but when they get to skateparks, they have a private session.
A boy in my Parents village died at a cross roads riding with no brakes. It may not have made a difference as he pulled out into the road from behind a wall but I can’t help wonder if slowing was easier, i.e he had a brake, he would have been less likely to roll out as loosing momentum would be easier.
I run two brakes but I’m old and have delusions if one day becoming Rob Ridge.
Back on topic avoid WinstanleysBMX, several friend have had nothing but problems dealing with them.
